MULTIPLE COCK.

I Specification of Letters Patent.

Patented Apr. 2, 1912.

Application filed March as, 1911 Serial No. 617,517.

To all whom. it may concern:

Be it known that I, PHILIP MUELLER citizen of the United States, residing at ecatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Multiple Cocks, of which the following is a specification.

My invention consists of a multiple cock particularly adapted for use in connection with water meter testers. While of the particular adaptation stated, however, it will be apparent upon an understanding of my invention that it may be used in part or as a whole in connection with gas or other fluid meter testers.

In the testing of meters it is found that a meter which will give correct indications of the amount of water flowing through it, by

a stream of one size, will not give correct indications when the water is caused to flow by a stream of another size. Thus water meters are very frequently found to be inaccurate when measuring water flowing in a stream of one size while they may be highly accurate when measuring water flowing by a stream of another size. Particularly is this true of large meters specifically designed to measure large quantities of water. \Vhile accurate in the measurement of large streams of water they are very often inaccurate in measuring small streams of water. The same thing is true of many average sized meters. It is, therefore, extremely desirable and of great importance that a meter should be tested measuring both large and small streams in order that error in the measurement of small streamsmay be corrected.

Heretofore when meter testers were used for testing meters on streams of varying sizes, the size of the stream has been adjusted by throttling and by the use of different sized discharge pipes or nozzles. The first of these devices is not satisfactory for the reason that it requires very accurate adjustment, and for the reason that the quantity of fluid flowing through the throttled orifice does not vary according to a regular law, but varies according to the shape of the throttled opening and according to the configuration oi the valve seat and disk, etc. The second of the devices mentioned is unsatisfactory for the reason that when the size of the discharge pipe is changed the connections must be made and broken with a resultant loss of time and increase in expense. It is highly desirable that besides being accurate a meter tester should be so equipped as to be capable of most rapid manipulation in order that the days run of' tested meters may be a maximum.

The multi 1e cock of my invention obviates all of t e above mentioned disadvantages. By the use of this cock, the size of the stream may be regulated with absolute exactness, and at the same time may be varied an desired amount with great ease. and rapidity. Specifically, I provide a valve body having a member with a valve opening for the flow offluid from one chamber of the body on one side of the member to un other chamber of the body on the other side of the member, and provided with means whereby the stream of fluid which flows through the opening may be constricted to any one of a number of predetermined sizes. In the preferred form of my invention the stream may be constricted to circular form of any one of a number of predetermined diameters, these diameters being chosen with respect to the sizes of the streams which the meter is supposed to measure in practice.

In the accompanying drawings I have shown one embodiment of my invention. This embodiment comprises in general a casing, a valve seat member, a valve disk member, one of said valve seat and disk members being an apertured member provided with a series of apertures of different sizes, means for moving the members relatively to bring any desired aperture into cooperative relation with the other member, means for clamping the valve disk member upon the seat of the valve seat member, and means for indicating the size of the particular aperture which is being used.

Referring to the drawings,-Figure 1 is a central, transverse section of the cock of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail of the indicating mechanism,and Figs. 4 and 5 are elevations of two of the apertured members employed. Fig. 6 is a central, transverse section of a modified form.

The valve casing is designated generally 10, and is provided with inlet and outlet openings 10 and l0".

[1 is the valve seat member which 'in this embodiment lies with its main body parallel to the side wall of the casing 10, thus dividing the interior of the easing into two chambers 12 and 13, one on each side of the valve seat member 11.

14 and 15 are the valve disk members which cooperate with the valve seat member 11.

16, 16 designate generally the means for clamping the disks to the seats, and 17, 17 the means for adjusting the valve disk members 14 and 15 with respect to the seat member 11, and 18, -18, the indicating and locking devices associated with the adjusting means 17, 17.

As shown, the body of the valve casing in th is embodiment is circular and relatively shallow, being somewhat disk-shaped. The

valve seat member 11 is provided with an eccentrically positioned circular aperture 19. The valve disk members 14 and,15 are each provided with a plurality of circular openings disposed on a concentric arc, the radius of which is equal to the radius of eccentricity of the opening 19 in the valve seat member 11. As clearly seen in Figs. 4 and 5, the apertures of the disk 14 are graded in diameter from a maximum to a minimum, while those of the member 15 are similarly graded in diameter in continuation of the graded series of apertures of the disk 14. The disk having the smaller apertures also has a large aperture the same size as the largest aperture in the other disk. (See Figs. 4 and 5.) In actual practice, these apertures in member 15 are made of diameters varying from one-t-hirty-second to fiveeighths inch, while those in member 14 are made of diameters varying from threefourths to two inches. The disk 15 has also a two-inch aperture. These valve disk memcollar.

bers are slidably mounted on the squared ends of stems 20 of the adjusting mechanism 17, these stems 20 passing centrally through the opposite walls 22 of the casing 10 and having their ends reduced in diameter jour-,

naled in the central valve seat member 11. The portions adjacent the squared ends are somewhat enlarged, as at 21, the outer shoulders of the enlarged portions being engaged by the side walls 22 of the casing 10, which side walls are removable. Thus the adjusting members 20 and the valve disk members are associated with the walls of the casing and held in position, but are at the same time freely removable with the side walls of the casing. By means of the hand wheels 23 on the stems 20 the members 14 and 15 may be revolved to bring opposite the opening 19 an aperture of any desired diameter.

The indicating means by which the size of the particular aperture 19* being. used is indicated comprises an indicating member 24 on each stem 20 in the shape of a flanged This collar is circumferentially slotted at a plurality of points 25 correspondoted at 27 between the ears 28 formed integrally with the outer walls 22 of the casing. The latch is normally pressed outward by a spring plunger 29 so that its end 30 engages in one of the slots 25, and is rovided with an operating handle 31 by which the pressure of the spring plunger may be overcome and the end 30 be moved from the slot engaged by it. The indicating member 24 is made adjustable with respect to the stem 20 for a purpose which will presently appear.

- The means 16 for clamping the valve disk members 14 and 15 to the valve seat member 11 comprises in each case a valve stem 32 provided with a common form of motive screw threads 33 engaged in the walls 22 ofv the casing, and a means in the form of a crow foot 34 engaging the respective valve disks. The valve disks are provided with inner and outer flanges 36 and 35, the flanges 35 being internally grooved and the flanges 36 exteriorly grooved to accommodate the ends 37 of-the crow feet which are shaped to fit them. Preferably these crow feet are swiveled on the ends of the stems 32 and their engaging ends 37 are connected by a circular ring of metal 38. In order to admit the rings 38 to the grooves the flanges 35 are cut-away for a distance, as shown in Figs. 4 and 5. By virtue of this construction the disks are moved perpendicularly to the seats, and tearing of the packings of the seat and distortion of the disk are prevented. This is valuable when there has been corrosion and the valve disk has stuck. A packing of a commonly used form 39 is provided between the stems 32 and the .walls of the casing, and operating handles 40, adjustable with relationto the stems 32 as shown in section on the left of Fig. 1, are placed on the ends of the stems for turning them.

With this understanding of the structural features of my invention, its operation and great resultant advantages ofuse should be apparent. By releasing the clamping means 16 by turning the ValKG handles 40 in the usual manner, and then releasing the stems 20 of the adjusting mechanism by pressing inward the handle 31 of the latch 26, the disk members may be adjusted to bring any desired opening 19 into register with the opening19. Thus for instance if it is desired to restrict the stream of flowing water to one of five-eighths inch diameter, the one of the stems 20 carrying the disk which has that aperture is turned until the slot 25 marked five-eighths inch comes opposite the held locked in adjusted position.

- disk 15 is clamped with its largest aperture in register with opening 19 when it is desired to constrict the stream by the smaller apertures of disk 14. -Thus it should be evident that any one of the apertures may be brought into register with aperture 19 and the diameter of the stream most quickly and most accurately regulated. By virtue of the provided means of adjustment of the handles 40 with respect to the stems 32, these handles may be so positioned as not. to be interfered with by the stems '20. By virtue also of the provided means of adjustment of the indicating and locking members 24 on the stems 20 these members may be so adjusted with respect to the valve disk members and the latch 26 as to permit of the positioning of the latch asshown in Fig. 2 where it will not interfere with the operation of the handles 40.

In Fig. 6 I show a modification which differsstructurally from the formjust de scribed in that only one valve disk member is used, as shown the left hand one 14. The right hand disk 15 and associated operating means are omitted, and the right side omitted, and the right side Wall is formed integral and non-removable. This valve is of more limited capacity than the valve of double construct-ion of the same diameter of valve disk, but operates in the same manner. There are many situations in which it may be preferable to use this construction.--

While I have described the best form of my invention now known to me, I desire not to be limited thereto, since it is ap-, parent that many changes may be made by those skilled in the art without departing from the broad idea of my invention.
